In-Vivo Visualization of Retinal Crystals in Bietti's Crystalline Dystrophy by Spectral Domain Optical Coherence Tomography

In this study, an attempt is made to assess in-vivo, the location of retinal crystals in a 39-year-old woman with Bietti's crystalline dystrophy using spectral domain optical coherence tomography (Spectralis SD-OCT). In this patient, it was possible to show the exact correspondence between the retinal crystals, as visualized by infrared frame, and the tiny hyper-reflective SD-OCT lesions that appeared localized in all retinal layers, from the RPE to the retinal nerve fibre layer.
